 Jeremy and Randell are brothers and each are trying to raise money for summer camp.
To help Jeremy raise money, his parents told him he could wash each of their cars once a week for $20.00 each. He has already earned $640.00. The football camp that he wants to attend costs $1,469.00.
To help Randell raise money, his parents told him he could mow the grass for them and both sets of grandparents once every 2 weeks and earn $28.00 for each lawn he mows. He has already earned $728.00. The lacrosse camp that he wants to attend costs $1,701.00.
If Jeremy and Randell each earn enough money to attend the camps of their choice, then from this point on (randell) needs to complete (idk what would got here) more chores than(jeremy)

is it asking you to fill in the blanks with their names if so i think it would be this.

Plz help me with the answer
UkoKoshka [18]

Answer:

<h2>y = 4</h2>

Step-by-step explanation:

Put x = 9 to the equation 3x + 4y = 43

(3)(9) + 4y = 43

27 + 4y = 43            <em>subtract 27 from both sides</em>

4y = 16            <em>divide both sides by 4</em>

y = 4

The weight of a puppy is 1.6 kg and the weight of a kitten is 750 g. What is the difference in their weights (measured in g)?
goldfiish [28.3K]
You would multiply 1.6kg by 1000 to get the amount of grams since 1000 grams equals one kilogram.

So 1.6x1000=1600

Then you would take 1600 and subtract 750 from it to get the difference which is 850g! Hope this helped :^)

A rectangular banner covers an area of 2 7/8ft2. The length of the banner is 3/4ft. What is the width of the banner in ft?
hichkok12 [17]

Answer:

Width of the rectangular banner is 3\frac{5}{6} ft.

Step-by-step explanation:

Area of the rectangular banner = 2\frac{7}{8} square feet

                                                    = \frac{23}{8} square feet

Area of rectangle is given by,

Area = Length × Width

Length of the banner = \frac{3}{4} feet

From the formula,

\frac{23}{8}=\frac{3}{4}\times W

W = \frac{\frac{23}{8} }{\frac{3}{4} }

    = \frac{23}{8}\times \frac{4}{3}

    = \frac{23}{6}

     = 3\frac{5}{6} ft

Therefore, width of the rectangular banner is 3\frac{5}{6} ft
